WILLIAM ZCCULLOUGH, OF NEW YORK, N. Y.

UNITEDSTATES' PATENT" O FICE.

GAGE.

SPECIFICATION forming part of Letters Patent No. 270,091, dated January 2, 1883, application filed May 11, 1882. (ModeL) To. all whom it may concern:

Be it known that WILLIAM M00 ULLOUGH, of the city, county, and State of New York, have invented a new and useful Improvement in Gages, of which the following is a full, clear, and exact description.

My invention seeks to improve that class of gages which are more especially used for gag than the other) to be used in combination with p a slotted head-block adapted to slide on the stock, the head-block having two gage surfaces or faces at right angles to the stock, which are the same distance apart that the marking points or blades are, as hereinafter more fully set forth, and pointed out in the claims. a

I provide the headblock with an ordinary gage-bar to be used for ordinary purposes, and this, in connection with the head-block itself and the main stock, constitutes a further feature of my invention.

Reference is to be had to the accompanying drawings,formingapartof this specification, in

;which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the under side of my new and improved gage. Fig.2 is a side elevation of the same, illustrating the manner of using the gage for marking or cutting the edge of a door. Fig. 3 is a similar view, illustrating the UlflllllBlZOf using the gage for marking or cutting the jainb of the door-casing; and Fig. 4 is a front elevation of the gage.

A represents the stock, which is by preference square in cross-section, and may be of any suitable length; and B represents the headhlock, which is adaptedto slide upon the stock in the ordinary way. The stock. is provided with the marking points or blades a and b, the latterbeing of considerable length, as shown in the drawings, and the head-block B is formed with the slot d, so that the block may he slid upon the stock past the point or blade b. ff are the opposite gage surfaces or faces of the head-block B, which are the same distance apart that the marking points or blades a and b are; and 0 represents the ordinary gage-bar, which slides in the head-block B,

and which is provided with the ordinary marking-point, c, the surface 9 of the head-block serving as its gage surface or face.

D is the thumb-screw for setting the bar 0, and E the thumb-screw for setting the headblock B at any desired position upon the stock A.

The distance between the surfacesfandj" of the head-block being exactly ,equalto the distance between the marking-points a and b, it will be seen that when thesurfacefis moved to and from the point a the surface j" will he moved an equal distance toward or from the point b, so'tha-t the distance between the surfacef and the point I) will always be exactly equal tot-he distance between the surface j" and the point a, so that a line or mark made with the point I), the surfacef being the gage, V

will always be the same distance from the object against which the face f is placed that a line or mark made with the point a will be from the surface against which the face f is placed as the gage, the head-block remaining in the same position.

In using my improved gage for hanging doors, or for marking or cutting the jamb J, the fac'ef of thehead-block will be placed against thejamb at J, as shown in Fig. 3, and the mark or out made by the point or blade I). For marking or cutting the edge of the door K the gage will be applied to the door as shown in Fig. 2, the surface or face f being placed against that side of the door the corner of which shuts againstthejamb at J, as shown, and the mark or cut made by the point or blade a. By this means it will be seen that the distance from thejamb at J to the mark made on the jamb will be exactly equal to the distance between the mark on the edge of the door and the side of the door which comes against the jamb, so that when the door is hung the side of thedoor will come properly against the jamb. I

The gage O is used in the ordinary manner.

Thus constructed it will be seen that the gage is fitted for a variety of work, and is cheap and simple, and when used for hanging doors 2. In a gage, the combination of the stock is very accurate and easily set and handled.

The combination, with the stock A, proand having two parallel faces, f and f, at the vided with the points a b, the latter being the J same distance apart as the points a and b of longest, of the sliding head-block B, provided the stock A, with the bar 0, provided with'one with the central slot, d, and gage surfaces or marking-point, c, substantially as specified.
